Hab. Mexico 21014, valley of Mexico (White"), temperate region of Vera Cruz (Sumi- 
chrast ®), Jalapa (Sallé+, de Oca®, Deppe'?, Hoge), Orizaba (Botteri *, le Strange), 
Totontepec (Boucard °), Oaxaca.—CoLomBia 1 °°. 
The range of this species is remarkable, inasmuch as it is completely severed into 
two parts. The northern section is restricted to Southern Mexico, and the southern to 
Central and Eastern Colombia. The whole of the intermediate country is occupied by 
the allied species B. gutturalis, apparently to the complete exclusion of B. albinucha. 
In Colombia it is by no means a common bird; but not only was it originally 
described from a Colombian specimen in the Paris Museum, sent by Candé from the 
neighbourhood of Cartagena *, but Mr. Sclater has in his possession a skin which is of 
the unmistakable make of the Bogota bird-hunters*; so that its presence in the south 
can hardly be questioned. 
In Mexico B. albinucha is well known, being, as Sumichrast says, one of the 
characteristic birds of the temperate region between the elevations of 2000 and 3600 
feet °. 
Mr. Sclater speaks of a specimen in his collection which has the throat orange- 
coloured, showing that the species varies in this respect just as Bb. gutturalis ®.

Olivaceus, alis et cauda nigricantibus illis olivaceo limbatis, capite sumno nigro, stria occipitali, regione post-

hypochondriis et crisso ferrugineo indutis. Long. tota 7:5, ale 3°3, caudex 3-4, rostri a rictu 0-7, tarsi 1:3. 
(Descr. exempl. ex Volcan de Irazu, Costa Rica. Mus. nostr.) 
Hab. Costa Rica (v. Frantzius+), Irazu (Arce, Rogers, Boucard*); Panama, Volcan de 
Chiriqui (Arcé 2). 
Though placed in a distinct genus by Dr. Cabanis, this bird may fairly be included 
in Buarremon, the only distinction being, so far as we can see, the greater strength of 
the tarsi and toes. Its habits seem to resemble those of B. brunneinucha. M. Boucard 
tells us* that it frequents the Volcan de Ivazu, going in pairs, which spend most of 
their time on the ground scratching in search of insects. 
The only extension of the range of B. capitalis beyond Costa Rica is the volcano of 
Chiriqui, where Arcé found it and sent us several specimens, one of which is now 
figured.
